Over the past 18 years, TAOANG products range from raw material bauxite to processing follow-up products brown fused alumina, finishing white fused alumina and dense fused alumina, bubble alumina, and fused alumina micro powder. The production process is fully controlled to achieve control of product quality and price.
1. Different raw materials: The raw material of brown corundum is bauxite, and there are also anthracite and iron shovel. The raw material of white corundum is alumina powder. 2, the color is different: because the content of alumina in white corundum is higher than brown corundum, so the color of white corundum is white, brown corundum is brown and black. 3. Different composition: Although both brown fused alumina and white corundum contain alumina, the alumina content of white corundum is above 99%, and the content of brown corundum alumina is about 95%. 4, the hardness is different: the hardness of white corundum is slightly higher than brown corundum. White corundum abrasive is a crystalline compound with good hardness and toughness. The crystal size is fine and the wear resistance is good. However, the production cost is high and the output is low, so the price is relatively high. The brown corundum abrasive has medium hardness, weak grinding effect and low price. 5, different performance: brown corundum has high purity, good crystallization, strong fluidity, low coefficient of linear expansion, corrosion resistance. White corundum has the characteristics of high purity, good self-sharpness, acid and alkali corrosion resistance, high temperature resistance and stable thermal performance. In comparison, the hardness of white corundum is higher than that of brown corundum. 6, the use of different objects: white corundum is used by some high-end users, because it has better cutting strength, polishing is also very good, mostly used in carbon steel, alloy steel, malleable cast iron, hard bronze, etc., while brown corundum is the market Commonly used, it is also relatively large in the market, mostly used for hardened steel, high speed steel, high carbon steel and so on. 7. Different smelting processes: Brown corundum is produced by high-temperature melting of bauxite, which is produced by redox reaction. White corundum is formed by melting and melting of bauxite.8. different uses: Brown corundum or brown fused alumina: used for grinding wheels, sand blasting, free grinding, resin grinding tools, coated abrasives, functional fillers, filter media, refractory materialsWhite corundum or white fused alumina: used in ceramics manufacturing, resin-bonded abrasives, sandblasting, polishing, grinding, precision casting and advanced refractory materials
